(Received 9 December 2011; accepted 9 December 2011; online 17 December 2011)

In the title compound, C19H15Cl2N3O2, the benzotriazole ring system is approximately planar [maximum deviation = 0.018 (2) Å] and its mean plane is oriented at dihedral angles of 30.70 (5) and 87.38 (4)°, respectively, to the furan and benzene rings while the dihedral angle between furan and benzene rings is 74.46 (6)°. In the crystal, weak C—H⋯N hydrogen bonds link the mol­ecules into chains along the b axis. ππ stacking inter­actions between the parallel dichloro­benzene rings of adjacent mol­ecules [centroid–centroid distance = 3.6847 (9) Å] and weak C—H⋯π inter­actions are also observed.

In recent years, there has been increasing interest in syntheses of heterocyclic compounds that have biological and commercial importance. Miconazole and econazole have been developed for clinical uses as antifungal agents. Similar structures containing benzimidazole ring in place of imidazole ring of miconazole and econazole have been reported showing more antibacterial activity than antifungal activity (Özel Güven et al., 2007a,b). Benzotriazole derivatives also exhibit a good degree of analgesic, anti-inflammatory, diuretic, antiviral and antihypertensive activities (Hirokawa et al., 1998; Yu et al., 2003; Kopanska et al., 2004). The crystal structures of miconazole (Peeters et al., 1979), econazole (Freer et al., 1986) and similar ether compounds (Özel Güven et al., 2008; Özel Güven et al., 2009; Özel Güven et al., 2010a,b; Özel Güven et al., 2011) have been reported, previously. Now, we report herein the crystal structure of a new benzotriazole derivative, (I).

In the molecule of the title compound (Fig. 1), the bond lengths and angles are generally within normal ranges. The benzotriazole [B (N1-N3/C7-C12)] ring system is approximately planar with a maximum deviation of 0.018 (2) Å for atom C9 and its mean plane is oriented with respect to the furan [A (O2/C2-C5)] and benzene [C (C14-C19)] rings at dihedral angles of A/B = 30.70 (5) and B/C = 87.38 (4) °. The dihedral angle between furan and benzene rings is A/C = 74.46 (6)°. Atom C6 is -0.033 (2) Å away from the plane of the benzotriazole ring and atom C1 is 0.050 (2) Å away from the plane of the furan ring, while atoms Cl1, Cl2, O1 and C13 are 0.0309 (5), 0.0223 (5), 0.0817 (11) and 0.0195 (18) Å away from the plane of the benzene ring, respectively.

In the crystal, weak C—H···N hydrogen bonds (Table 1) link the molecules into chains along the b-axis (Fig. 2). There also exists a ππ contact between the benzene rings, Cg4—Cg4i, may further stabilize the structure [centroid-centroid distance = 3.685 (1) Å; symmetry code: (i) 2 - x, -y, -z; Cg4 is the centroid of the ring C (C14-C19)]. A weak C—H···π interaction (Table 1) may stabilize the structure.

Experimental top

The title compound, (I), was synthesized by the reaction of 2-(1H-benzotriazol-1-yl)-1-(furan-2-yl)ethanol (Özel Güven et al., 2012) with aryl halide using NaH. 2-(1H-Benzotriazol-1-yl)-1-(furan-2-yl)ethanol (219 mg, 0.95 mmol) was dissolved in DMF (4 ml). NaH (38 mg, 0.96 mmol) was added to the solution portionwise. After stirring the mixture a few minutes, 2,4-dichlorobenzyl bromide (229 mg, 0.95 mmol) was added dropwise. Then, the reaction mixture was stirred additional 3 h at room temperature. Adding methanol (5 ml), the reaction was stopped. After evaporation of the solvent, dichloromethane was added to the reaction mixture and extracted with water. Then, the organic phase was separated, dried, filtered and evaporated. The precipitate formed was purified by column chromatography using chloroform and crystallized from 2-propanol to obtain colorless crystals suitable for X-ray analysis (yield; 295 mg, 80%).

Refinement top

H atoms were positioned geometrically with C—H = 0.98, 0.93 and 0.97 Å for methine, aromatic and methylene H, respectively, and constrained to ride on their parent atoms, with Uiso(H) = 1.2 Ueq(C).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2sigma(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
